I stripped down my MagicMirror configuration as well, so that we know that another module is not interfering. The modules that ARE on this config include: alert, updatenotification, MMM-ModuleScheduler, clock, MMM-AlarmClock, MMM-DarkSkyForecast, and MMM-Screencast. Here are the errors in the console running MagicMirror and accessing on Chrome with those modules running.

However, I then stripped ALL modules EXCEPT MMM-DarkSkyForecast and rechecked the console. I get NO errors, and the log is as follows, but the modules still loads infinitely, with no display of weather (see screenshot, below):

So after adding in one module at a time to determine which one was throwing the errors I posted above, it is the default MagicMirror “clock” module, and I do not believe it is the cause of the MMM-DarkSkyForecast problems.

I posted an issue on your module link in GitHub, but no response yet. Please see this link for details. Both the config in the link as well as the one below do the same thing…loading infinitely.

			module: 'MMM-DarkSkyForecast',
